Followings could be some reasons for raise in fuel consumption of a ship:
1- Bad quality fuel
2- faulty fuel pump/ fuel valves (main engine)
3- ship's bottom being dirty
4- faulty turbo charger (main engine)
5- blow by of the piston rings (main engine)
5- leaky inlet/exh. valves (main engine)
6- leakage in fuel system (pipping)
7- faulty fuel oil separator
8- Unprefect bunckering
9-.....etc.

What is the formula of fuel oil consumption of cargo ship?
First you need to convert the transit time into hours by multiplying the number of days by 24; you need to add any remaining hours to this result. Then you need to know how much fuel the ship takes per hours. Finally, you multiply the number of hours by the best fuel consumption.
What is the cube rule for Marine slow speed engine fuel consumption?
In operation, the ship’s fuel consumption depends on its hull condition and the speed at which it is operated. When a ship is designed, naval architects optimize the hull and power plant to a prescribed design speed which may be, for example, 15 knots for a bulk carrier or 18 knots for a small container ship. Operation of the vessel at lower speeds results in fuel savings because of the reduced water resistance, which, according to the ‘cube rule’, will be approximately proportional to the cube of the proportional reduction in speed:F = F*(S/S*)^awhereFis the actual fuel consumption (tons/day),Sthe actual speed,F*the design fuel consumption, andS*the design speed. The exponentahas a value of about 3 for diesel engines and about 2 for steam turbines. It follows from the cube rule that the level of fuel consumption is very sensitive to speed.
What is the Fuel consumption of a cargo ship?
The amount of fuel burn for a marine vessel is dependent on multiple factors. These include the vessel size, tonnage, propulsion type (fuel oil, diesel, nuclear, etc.), speed, marine conditions, and the engine efficiency itself.
How do you calculate the Specific Fuel Oil consumption on a ship?
SFOC = Mass of fuel burnt to produce a unit power in 1 hour. SFOC = Mass of fuel / kW in 1 hour Density = Mass / Volume Mass of fuel = Density X Volume SFOC = Mass of fuel / kW power in 1 hour You get the value is Kg, But to specify in Grams you have to multiply the answer by 1000. Let us calculate SFOC with given values, For a ship X, the daily fuel oil consumption is 75 Tonnes. Power in kW = 11520 BHP power = 15,448 To calculate SFOC in g/ kWhr, Total fuel consumption / day = 75 tonnes Fuel consumption / Hour = 75/24 = 3.125 Tonnes = 3125 Litres Specific Gravity of fuel used = 0.9375 (Usually given in BDN- Bunker delivery note) SFOC = 3125 X 0.9375 /11520 SFOC = 0.2543(Litres) X 1000 (To get it in Grams/kwhr) SFOC = 254.3 g/kWhr
Where do you go after putting fuel in the ship astro nights?
After putting fuel in the ship, you go to the moon. The ship crashed and you get to make your own ship. Your can change the design of the ship anytime.
How is fuel consumption on a ship calculated?
I believe it would be either gallons per hour or tons (of fuel) per hour. Well ships vary in their sizes and so does the fuel consumption. As i have been sailing for last 10 years, ive seen ships consumtion of oil ranging from 35 tons/day to 110 tons/day. Fuel consumption on board ship is by taking flowmeters which are installed on the fuel oil line going to the engines. The reading is taken everyday or after some maneuvering is being done. The difference in the reading gives the amount of fuel in litres consumed. This quantiry in leters when multiplied with the temperature correction factor and then converted into mass by multiplying with the density of fuel Hence we get the fuel consumed per day. To make sure the calculations are going fine..at regular intervals the quantiry remaining in the fuel tanks is being checked and functioning of flowmeters along with any accidental seepage is confirmed.
Where is fuel stored on a ship?
fuel tank
How do you fuel a cruise ship?
Go to a cruise ship gas station! ;) Or in port a fuel hose would be connected to the ship to refuel.
Why does mass of a body vary with velocity?
Here's one way of looking at it: you have to consider the problem from two different frames of reference. Let's set one as a spaceship accelerating at some speed above 0.5c. The other will be a rest frame, the inertial frame from which the ship departed. Each frame contains an identical clock. Each clock, tested before separation, ticks off identical seconds. If I send the ship out and back at high acceleration, then compare the elapsed time on both clocks, I will find that the times vary. Seconds on the moving clock were stretched when compared with those of the rest clock, though time appeared to pass normally on the ship. Consider all of this in terms of fuel consumption. From my frame of reference within the ship, all clocks run normally, so I register a constant fuel consumption for what I expect to be constant acceleration. But from the external (rest) frame, I can calculate that the moving clock has stretched each second in proportion to each increase in speed by the Lorenz time dilation factor, so I record the ship's fuel consumption as being stretched over longer and longer intervals as the ship accelerates. In fact, what is perceived in the ship as constant fuel usage appears to be decreasing usage from the rest frame. It will take longer and longer intervals (or an increasing rate of fuel consumption) to accomplish each increasing increment of velocity as the same amount of energy is expended over increasing intervals. From the ship, I see progressively smaller increases in velocity from the same rate of fuel expenditure. By any method of measurement, this equates to an increase in mass. It appears to take progressively more energy to accelerate the ship by any given increment.
The reason a ship floats is because?
The basic reason that a ship floats is that the enclosed volume in the ship's hull is greater than the volume of water which has the same mass as the ship.
Where is the gas tank on a cruise ship?
There is no gas tank on a cruise ship. There are fuel tanks, which hold the bunker fuel and they are usually located in the bilge of the ship. (Compartments below the waterline)
Will balloons raise a sunken ship?
No, balloons would not be able to raise a sunken ship on their own. The process of raising a sunken ship typically involves using specialized equipment such as cranes, salvage pontoons, or airbags to lift the ship to the surface.
